Title Athena mirror module

Description
This ‘mirror module’ – formed of 140 industrial silicon mirror plates, stacked together by a sophisticated robotic system – is destined to form part of the optical system of ESA’s Athena X-ray observatory.

Due to launch in 2031, Athena will probe 10 to 100 times deeper into the cosmos than previous X-ray missions, to observe the very hottest, high-energy celestial objects. To achieve this the mission requires entirely new X-ray optics technology.

Energetic X-rays don’t behave like typical light waves: they don’t reflect in a standard mirror. Instead they can only be reflected at shallow angles, like stones skimming along water. So multiple mirrors must be stacked together to focus them: ESA’s 1999-launched XMM-Newton has three sets of 58 gold-plated nickel mirrors, each nestled inside one another. But to see further, Athena needs tens of thousands of densely-packed mirror plates.

A new technology had to be invented: ‘silicon pore optics’, based on stacking together mirror plates made from industrial silicon wafers, which are normally used to manufacture silicon chips.

It was developed at ESA’s ESTEC technical centre in the Netherlands, and patented by ESA, invented by an ESA staff member with the founder of cosine Research, the Dutch company leading an European consortium developing Athena’s optics.

The technology was refined through a series of ESA R&D projects, and all process steps have been demonstrated to be suitable for industrial production. The wafers have grooves cut into them, leaving stiffening ribs to form the ‘pores’ the X-rays will pass through. They are given a slight curvature, tapering towards a desired point so the complete flight mirror can focus X-ray images.

“We’ve produced hundreds of stacks using a trio of automated stacking robot,” explains ESA optics engineer Eric Wille. “Stacking the mirror plates is a crucial step, taking place in a cleanroom environment to avoid any dust contamination, targeting thousandth of a millimetre scale precision. Our angular resolution is continuously improving.”

“Ongoing shock and other environmental testing ensures the modules will meet Athena’s requirements, and the modules are regularly tested using different X-ray facilities.”

Athena’s flight mirror – comprising hundreds of these mirror modules – is due for completion three to four years before launch, to allow for its testing and integration.

Each new ESA Science mission observes the Universe in a different way from the one before it, requiring a steady stream of new technologies years in advance of launch. That’s where ESA’s research and development activities come in, to early anticipate such needs, to make sure the right technology is available at the right time for missions to come.

Long-term planning is crucial to realise the missions that investigate fundamental science questions, and to ensure the continued development of innovative technology, inspiring new generations of European scientists and engineers.

Science is everywhere at ESA. As well as exploring the Universe and answering the big questions about our place in space we develop the satellites, rockets and technologies to get there. Science also helps us to care for our home planet. All this week we're highlighting different aspects of science at ESA. Join the conversation with #ScienceAtESA.

7 February 2019
For some, the concept of ‘science’ may seem difficult or even boring, particularly if it was taught poorly at school. However, with all of us facing the consequences of a rapidly changing world, science is fundamental to implementing adaptation and mitigation strategies. Thanks to satellites delivering critical science, we are better placed than ever before to cope with the challenges ahead.

It goes without saying that the environment has a huge bearing on our quality of life. Clean air and the availability of freshwater and food are among the mere basics, and indeed among the UN’s sustainable development goals. But urban expansion, industrial growth and other aspects of modern living set against a backdrop of climate change and a rising global population are also high up on the list of global concerns.

Much of human history has been influenced directly or indirectly by Earth science. But one of the biggest scientific challenges we face today is to understand the intricacies of the Earth system and how humans are affecting the delicate balance of the natural world.

The vantage point of space provides a window on the world like no other, through which to understand and monitor our changing planet.

ESA has been dedicated to observing Earth from space ever since the launch of its first Meteosat weather satellite in 1977. This first mission and the subsequent series of meteorological satellites along with ERS and Envisat environmental missions, which delivered a wealth of information about our land, atmosphere, oceans and ice, led to a greater understanding of our home planet in a few short decades.

Dedicated to addressing key scientific challenges identified by the science community, while demonstrating breakthrough space technologies and observing techniques, ESA’s more recent series of Earth Explorer missions are deemed among the best scientific satellite missions in the world.

And, conceived just 20 years ago, Europe’s Copernicus programme is in full swing. With seven Copernicus Sentinel satellites already in orbit delivering a mind-boggling amount of data for services that help to address today’s challenges such as urbanisation, food security, rising sea levels, diminishing polar ice, natural disasters and, of course, climate change.

Thanks to these missions along with satellite missions from other space agencies around the world, and the global efforts to work together to realise new science that ultimately benefits the world at large, we are able to take the pulse of our planet from space so that environmental issues can be addressed.

Science is everywhere at ESA. As well as exploring the Universe and answering the big questions about our place in space we develop the satellites, rockets and technologies to get there. Science also helps us to care for our home planet. All this week we're highlighting different aspects of science at ESA. Join the conversation with #ScienceAtESA.
